BELL.

SPECIFICATION forming part of Letters Patent No. 703,332, dated June 24,1902.

Application filed April 25, 1902. Serial No. 104,694. (No model.)

To all whom it may concern:

Be it known that I, PHILIP C. ARNOLD, a citizen of the United States,and a resident of East Hampton, in the county of Middlesex and State ofConnecticut, have invented certain new and useful Improvements in Bells,of which the following is a specification.

The invention relates to bells, and more particularly to the class ofbells in which a retary striking mechanism is used, the strikers ofwhich upon rotation are projected against the gong to cause the propervibration and sounding of the gong.

The object of the invention is to provide a suitable contact member uponthe gong to be sounded with which the rotary strikers will come incontact as the striker-plate is rotated and to provide a contactmemberwhich will produce a perfect sounding of the gong.

A further object is to make the contact member an integral part of thegong, so that there can be no chance of flat sound, which" is so oftenpresent in gong-bells where the contact members or lugs are sweat on orcast in the gongs, and at the same time to produce this contact memberby striking it up from the solid stock of the gong without altering thedensity of the gong at any point.

A further object is to produce a bell simple so in construction and onewhich a gong struck out of sheet metal can be easily and cheaply made. 1

Referring to the drawings, Figure 1 is a plan view of a bell embodyingthe improve- 3 5 ment with a portion of the gong broken away to showconstruction. Fig. 2 is.,a view looking at the inside of the gong. Fig.3 is a side View of the gong. Fig. 4 is a detail View of a portion ofthe gong adjacent to the contact member. Fig. 5'is a'rdetail View of amodified form of the device in which the lug is forced from the body ofthe gong.

In the accompanying drawings,the numeral 1 denotes the base-plate, and 2the gong, of a bell, the striking mechanism for which is carried uponthe base-plate. This striking mechanism comprises a thumb-lever 3,pivoted to the base-plate and having at its outer end a segmental racket,engaging a pinion 5, secured to and adapted to drive a gear 6, whichlatter meshes with a pinion 7, secured to the rotary striker-plate S.The striker-plate has struck up from it lugs 9 10, which pass throughperforated strikers l1 l2 and also through a retaining-plate 13. Thisretaining-plate bears frictionally upon the strikers 11 12 and c0ntrols,to a certain degree, their movement. Obviously as the striker-plate isrotated through the intermediate gearing by a movement of thethumb-lever 3 the strikers 11 12, 6o impelled by the centrifugal action,will be thrown outward and caused to engage the contact member 14:,which projects from the inner surface of the gong and lies in the pathof movement of the strikers. Several revoo5 lutions of the striker-plateare effected by a single oscillation of the thumb-lever, and thus thestrikers 11 12 are repeatedly and successively brought into engagementwith the projecting contact member 14, and the perfora- 7c tions inthese strikers permit them to rebound, and thus prevent impeding of thesound of the gong.

The contact member 14: is formed by forcing inward a portion of thestock of the gong by any suitable die, leaving a rectangular opening 15through said gong. In the case of struck-up gongs there are verymaterial advantages in using a lug or contact member of thisdescription, as it may be formed inte- 8o gral with the gong and beingof absolutely the same material and having the same density the blow ofthe strikers against it will cause a perfectly clear and perfectvibration of the gong. The form of the lug l t'is entirely immaterial,although it is shown in the drawings as substantially rectangular, butobviously any form of die might be used, giving various forms to thelug, and so long as this lug is forced inward to a suflicient degree tolie in the path of movement of and be engaged by the strikers it answersall requirements.

In fact the only requirement is that the lug shall be formed of the samematerial and without increasing the thickness or density 5 of the gongin any particular part.

It is to be observed that incast bells it ha been the practice to cast alug upon the inside of the gong, and thus at one point, at

least, of the gong its thickness is materially mo increased, and in facta mass of metal is interposed which retards the proper and clearsounding of the gong. By striking the contacting lu'g out of thematerial a much better action' is secured. The gong contains preciselythe same amount of material as though no lugs projected from it.

In Fig. 5 of the drawings there is shown a slightly-modified form of thedevice, and in this case the lug is formed by two parallel cuts in thegong and forcing the material between said cuts inward to a sufficientdistance to form the contact member.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A bell provided with a gong havingwa contact-lug formed integral withand struck out of the material of the gong.
